<p>Since Japan is the land of earthquakes, the seismic design is very important for the design of civil engineering structures and the design of architectural structures in Japan. The seismic design standard has been revised by the damage of earthquakes in the past. After the 2011 off the Pacific coast of Tohoku Earthquake, there is the need for Anti-Catastrophe Performance and redundancy to have the measures for Unanticipated Earthquake in the seismic design of Japan.</p><p>Therefore, the authors developed the new method of the reinforcing bar arrangement. The new method can enhance dramatically ductility capacity in the RC column, so it is possible to give sufficient redundancy against Unanticipated Earthquake. The authors think that it is a very effective technique in the seismic design. In this report, we report the performance evaluation method of the RC column by the new method and the construction results.</p>
